Klein Bottle

$65 USD

Here’s what Felix Klein had in mind back in 1882, when he first dreamed of a closed, one-sided surface. It’s elegantly curved, with a side loop making a transverse puncture at the nexus. An Acme Classical Klein Bottle is big enough to show to a classroom, yet slides easily into your backpack for trips across the Yukon. With its center of gravity directly over its base, your Acme Classical Klein Bottle stands on its own no need for extraneous stands, complex levitation apparatus, or unreliable anti-gravity fields. Indeed, in the absence of external forces, its polhode rolls without slipping on the herpolhode lying in the invariable plane.
